1.1 Designated use
The analyzer CA 70 is a compact analysis system for photometric measurement.
It is especially designed for the monitoring of aluminium, chromate, copper, iron,
total hardness, manganese or silicate in industrial water and waste water.
Any other use than the one described here compromises the safety of persons and the
entire measuring system and is, therefore, not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.
1.2 Installation, commissioning and operation
Please note the following items:
•Installation, electrical connection, commissioning, operation and maintenance of the
measuring system must only be carried out by trained technical personnel.
The technical personnel must be authorised for the specified activities by the system
operator.
•Technical personnel must have read and understood these Operating Instructions
and must adhere to them.
•Before commissioning the entire measuring point, check all the connections for
correctness. Ensure that electrical cables and hose connections are not damaged.
•Do not operate damaged products and secure them against unintentional
commissioning. Mark the damaged product as being defective.
•Measuring point faults may only be rectified by authorised and specially trained
personnel.
•If faults can not be rectified, the products must be taken out of service and secured
against unintentional commissioning.
•Repairs not described in these Operating Instructions may only be carried out at the
manufacturer’s or by the Endress+Hauser service organisation.
1.3 Operational safety
The analyzer has been designed and tested according to the state of the art and left the
factory in perfect functioning order.

3.3 Installation instructions
To install the analyzer at the intended location, proceed as follows:
1. Place the analyzer in position and secure it. For the installation dimensions, please
see chapter 3.2.
! Note!
A wall bracket is available as an option for mounting the analyzer (→Chap. 8
“Accessories”).
2. Lay the drain pipe for the reaction products. Where possible, use fixed pipes (PVC
or PE, internal diameter ¾" with 3% incline).
3. Connect the sample transfer.
! Note!
The sample can be obtained as follows:
–Directly or after a reversible flow filter or a cross current filter by means of a small
pump (rating approx. 300 ml/min), suitable for clear media, e.g. in the discharge
channel of a sewage treatment plant
–From a sedimentation tank or after microfiltration; this is practical for media
containing flocculants,
e.g. in an activated sludge basin
–Sample conditioning using ultrafiltration for heavily soiled media,
e.g. from the primary settling tank.
For questions regarding sample conditioning and its automation, please contact
Endress+Hauser Service or the Endress+Hauser Sales Centre responsible for your
region.
4. Connect the tubes from canisters containing reagents, standard and cleaning
agents to the following nozzles:
5. Tighten the pump hoses onto the sample pump and onto the reagent pump.
6. Set the pressure at the hose bed throttle valve (→Fig. 9, P. 35, item D) such that
sample and reagent are fed in without bubbles.
This completes the installation process. Now carry out the installation check and
proceed according to chapters 4 (“Wiring”), 5 (“Operation”) and 6 (“Commissioning”).
3.4 Post-installation check
•After mounting, check that all connections are secure and leak-tight.
•Ensure that the hoses can not be removed without effort.
•Check all hoses for damage.

Terminal assignment for two-channel version
! Note!
•The terminal block for mains connection (terminals L, N, PE) is situated on the left of
the main board on the cooled version.
•Alarm values 1 and 2 do not need to be connected if the PLC sets its own alarm values
at the analog output.
•When using a sample conditioning system:
Connect terminals 57 and 53 on the CA 70 to the corresponding terminals on the
sample conditioning system. For the allocation of these terminals, please see the
sample conditioning system operating instructions.
•If there is a 24 V voltage at terminal 57, the analyzer will not begin measurement
(sample not ready). To start measurement, the voltage must stay at 0 V for at least
5 seconds.
•The power supply line can be connected directly to the analyzer or via a main switch
to the sample conditioning system.

! Note!
•Always synchronise calibration and flushing time.
•Carry out flushing with standard cleaning solution approx. 3-4 hours before the next
calibration.
Flushing with special cleaning solution (e.g. hydrochloric acid) has a lasting effect on
calibration. Therefore, carry out this cleaning after calibration.
Date of the
1st Calibration 01.01.96 00:00... 31.12.95 23:59
Time of 1st calibration (DD.MM.YY, time hh.mm.
After each change the instrument does not wait for
the calibration interval. If the calibration is to start
immediately, set the time in the past.
Analyzers are delivered pre-calibrated.
–Start 1st calibration 48 hours after the initial start-
up at the earliest (warm-up phase)
–Set the time to 8:00 to reproduce impacts on
calibration in the curve.
–If you have started a calibration manually, you
should re-define the time of the 1st calibration
because the interval is dependent on the last
calibration.
Calibration interval 0 ... 720 h
48 h
Time between two calibrations.
The "0 h" setting stops calibration.
Recommended: calibration interval of 48 ... 72 h.
Calibration solution 0.00 ... 2.50 mg/l -Cr

5.3.4 Menu "CONFIGURATION"
! Note!
Some settings that can be made in this menu affect the defaults in the "PARAMETER
ENTRY" menu. In view of this, complete the "CONFIGURATION" menu first during initial
start-up.
Navigate through the main menu with the
W key to the "CONFIGURATION" option and
press the
F key, to move forward within this sub-menu and the K key, to return to the
previous option. The settings can be changed within the individual options with the
V
and W keys. With the H key, you can return to the main menu at any time.

Photometer Depending on spezification,
e.g. CR-A
This setting displays the parameter that is being
measured (e.g. CR-A). This is defined by the
product specification and set in this option at the
factory. Do not change the value. Otherwise, you
will receive an "Incorrect photometer" error mes-
sage.
Default settings yes / no
When "yes" is selected, all previously changed
settings are reset to the factory settings. In
addition, the date for the 1st calibration and for the
1st flushing are set to the day after
commissioning.
Measuring unit mg/l -Cr / mg/l
mg/l -Cr
Measuring unit selection is dependent on the type
of photometer. You can also select whether you
want the concentration of the ion (e.g. chromate)
or the concentration in reference to the element
(chromium in this case) to be displayed. This
setting also affects the scope of the measuring
range.
Calibration factor 0.20 ... 5.00
1.00
The calibration factor is the ratio of the measured
concentration of the calibration standard to the
pre-defined concentration of the standard (see
"PARAMETER ENTRY", calibration solution). The
deviation results from factors such as reagent
ageing, ageing of constructive components, etc.
The calibration factor compensates for these
effects.
CA 70 checks the registered calibration factor
logically. If the factor lies outside of the error
tolerance, the calibration is automatically
repeated. If the repeat also lies outside, an error
message appears and the analyzer continues to
work with the most recently registered, logically
correct factor.
The last 10 calibration factors are filed in the
memory with the date and time and can be
retrieved by pressing the
J key.
The calibration factor ca be changed manually.

If the sample is to be diluted between taking the
sample and the analyzer, the dilution factor has to
be entered here.
Delay to sample 20 ... 300 s
80 s
Dosing time for sample or standard (20 ... 120 s).
During this time, the entire system is flushed with
sample or standard, so when the reagent is added
there is definitely only fresh sample in the mixer. If
there is sufficient sample available, select the
highest possible value.
Analog output1
0 ... 20 mA / 4 ... 20 mA
4 ... 20 mA
Selection for the scope of channel 1 measuring
range.
If the concentration measuring range is 0 ... 5 mg/l,
this corresponds to 0 mg/l either 4 mA or 0 mA.
The end of the measuring range is the same in
both cases at 20 mA, so that for every model there
is a different gradient (calibration factor).
Analog output 2
Two channel version only!
Selecting scope of channel 2 measuring range.
The scopes of the measuring range are
independent of each other for channel 1 and
channel 2 and are determined by the start of
measuring range (channel 1 / channel 2) or end of
measuring range (channel 1 / channel 2) setting in
the "PARAMETER ENTRY" menu.
